Gold Molokai (IMAGE) Cell Press Caption This picture shows an undescribed species of Ariamnes from Molokai, Hawaiian Archipelago. Gillespie et al. describe an adaptive radiation of stick spiders that demonstrate repeated evolution of a discrete set of ecomorphs -- gold (shown here), dark, and matte white. The deterministic evolution of forms is associated with camouflage against a limited set of island predators, reduced dispersal and cursoriality, coupled with conserved pathways of color formation.
